THRASHING -MACHINE.

SPECIFICATION forming part of Letters Patent No. 326,991, datedSeptember 29, 1885.

Application filed July 11, 1884.

To aZZ whom it may concern;

Be it known that I, JAMES E. KIMBLE, a citizen of the United States,residing at Vicksburg,county of Kalamazoo, State of Michigan, haveinvented a new and useful Improvement in Thrashing-Machines, of whichthe following is a specification.

My invention consists in certain improvements in thrashing-machines,hereinafter described and claimed.

In the drawings forming a part of this specification, Figure l is a sideelevation, parts being broken away; Fig. 2, an enlarged broken port-ionof Fig. 1; and Fig. 3 is a cross-section on line 1 l in Fig. 2,enlarged.

The frame of the machine is composed of the upper beams, A, and thelower truss composed of the beams B B, oppositely inclined, crossingeach other approximately at a point midway of their length, and takingthe place of the usual sills at each lower side of thrashingmachineframes, and to said upper beams and lower truss the vertical beams arebolted, Fig.1. The construction on the opposite side of the frame (nothere shown) is the same as just described. By the use of these trussesthe frame is stronger and less complicated, forming convenient supportsfor shaft-bearings at a proper location, and affords more room beneaththe frame than in prior constructions. Further, the truss-beams may beof lighter material than the base-beams of machines otherwise formed,and yet, owing to the peculiar form of the truss and its connection withthe vertical beams of the frame, it constitutes a completesupporting-brace to the entire frame-work, preventing the tension-strainof the belts, 850., and the jolting of the machine while in transit fromspringing,warping,or racking the frame in any manner. It alsofacilitates turning the forward trucks, as they cannot conflict with theinclined truss-beams, but readily pass under in the act of turningaround.

The bottom of the straw-shaker F is composed of slats n, the rear edgeof one resting on the forward edge of another, thus forming a tightbottom, which throws the straw and grain along onto the riddle F whenthe shaker oscillates endwise. The riddle F has a bottom composed ofslats r r, set at like angles to the slats n, with an opening betweenthe overlap ping edges, to allow the grain to pass through (No model.)

and the straw to pass on out of the machine onto the strawelevator, asin such machines.

The grain-board and cleaner beneath the riddle are to be considered inother applications; hence no detailed description is herein given.

The straw-shaker and riddle are pivotally suspended in a manner tooscillate in opposite directions toward each other by means of thehangers a a. These hangers are pivoted at the upper end to the frame onboth sides of the machine, and are connected at the lower ends by thefork-rods, which pass through the side walls of the shaker and riddle ina manner to turn therein. The connection of the forkrods and hangers ismade adjustably secure by means of set-screws.

It is desirable to intercept the straw and grain after it passes fromthe cyli nder 0 through the mouth Eof the cylinderchamber in a mannerthat they will fall on the forward portion of the shaker F, and withoutletting any of the grain and straw fly through the machine. Beatersheretofore used have been so constructed and located that the straw andgrain either fell in the wrong place, or some flew through unagitated,as the passages from the cylinder-chamber became clogged up.

The beater in this machine is provided with only three wings, a",radiating from an axis at equal distances from each other. The beater islocated immediately in the rear of the discharge-opening E of thecylinder-chamber. The beater-axis is on ahorizontal plane with thecylinderaxis. In connection with this location of parts, thebeater-wings a are of such a width as to fill the space in .themachinetrunk above the axis of the beater. In the operation two of thewings, during the revolution of the beater, will always be presentedflatwise to the discharge-opening E, intercepting the straw and grain,thoroughly beating the same and causing them to fall on the shakerFalittlein the rear of thebeater. When more than the two wings arepresented in the path of the discharge, the third oneis presentededgewise, as in Fig. 1, thus forming no substantial obstacle to thedischarge. These results can only be accomplished by the use of a beaterwhen said beater is provided with only three wings and proportioned andlocated in relation to the discharge-opening E and the space in theInachinetrunk, as shown. The reason 5,

that a less number than three wings will not till the space of thecylinder-discharge, and hence will not intercept all of the grain andstraw, and a greater number than three wings will choke up thecylinder-discharge, retarding the passage of the grain and straw, andhence necessitate running the machine at alower rate of speed. I

The axle of the cylinder extends laterally beyond the bearing h at oneside, and is provided with a band-wheel, f, having a central surfaceabutting against the end of the bearing h. This wheel f is detachablykeyed to the axlem by means of aset-screw, Fig. 3. Thus by moving thecylinder to the right, leaving a little space between the left-hand endand its bearing,and keyingthe wheelf snugly against the bearing h, as insaid figure, the cylinder is prevented from pounding against itsaxlebearingswhen being drawn from one location to another by thejoltingof the machine, and

Having thus described my invention, what I claim as new i's l. Athrashing-machine frame composed of 5 nation of vertical frame-beams andinclined crossed truss-beams connecting with and supporting and bracingsaid frame-beams, substantially as set forth.

3. The combination ofa thrashing-machine cylinder having an extendedaxle end, the cylinder-bearings, and a band-wheel secured on said axleend, having a central portion abutting against a cylinder-bearing,substantially as set forth.

4. The combination of a thrashing-machine cylinder having the extendedaxle end, the cylinder-bearing, a band wheel having a central portionabutting against the cylinder-bearing, and a set-screw securing theband-wheel to said axle end, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in thepresence of two witnesses.

JAMES E. KIMBLE.
